The effect of the amount and the timing of single top-dressing application of Ammonium sulfate fertilizer on the growth and yield of Akitakomachi rice (Oryza sativa L.) was investigated in this study. Two amounts (20kg.ha-1 and 50kg.ha-1) of Ammonium sulfate ((NH4)2SO4) fertilizer were applied at three timings;14 days after transplanting, panicle initiation, and flowering respectively, giving six treatments (14DAT:20, 14DAT:50, PI:20, PI:50, FL:20 & FL:50). A Randomized Complete Block Design (RCBD) with three replications was used. Growth data were collected on plant length, number of tillers and leaf color, and calculated yield and yield components were determined. Plant length was significantly higher in 14DAT:50 and PI:50, and lowest in FL:20 and FL:50. Tiller number was higher in 14DAT:50 compared to the other treatments. 14DAT:50 and PI:50 produced the highest number of panicles per m2. PI:20 and PI:50 had the highest number of spikelets per panicle. The 1000 grains weight was highest in PI:50 and lowest  in 14DAT:50. The highest yields were obtained in 14DAT:50 and PI:50, while FL:20 and FL:50 produced the lowest yields. The results showed that for nitrogen (N) single top-dressing application, high amounts increase both the plant growth and the grain yield if the application is done at vegetative stage or at panicle initiation stage. However, if the nitrogen (N) amount is too high, there exist the risk that the plants may lodge.

Initiation Stage

A field experiment was conducted to observe the osmolyte-induced water deficit stress mitigation during the panicle initiation stage in transplanted rice (Oryza sativa L. cv. BRRI dhan72). At the panicle initiation stage, plants were simulated with four levels of water regimes viz., well-irrigated (D0), water deficit for 5 d (D1), 10 d (D2) and 15 d (D3). Plants were treated with or without 10 mM of proline (Pro) and trehalose (Tre) as foliar spray started at mid-vegetative stage and continued till the end of stress period. Results revealed that water deficit stress drastically reduced most of the plant morpho-physiological attributes while other yield contributing characters were also affected due to prolonged water deficit stress. However, exogenous application of osmolytes like Pro and Tre significantly increased all those morphological, physiological and yield contributing parameters. Foliar addition of osmolytes concomitantly decreased the number of non-effective tillers hill-1 and the number of unfilled grain panicle-1 under water stress condition. Although both the osmolytes performed well under multiple duration of drought stress, the application of 10 mM Pro markedly improved all growth and yield contributing parameters under D1 water deficit stress compared to other stress durations. Hence, it may be concluded that the use of osmolytes would be a prospective remedy against moderate water deficit stress in transplanted rice production.

       Rice is a food that produces rice. This food is a staple food for most Indonesians. Even as a staple food, rice can be replaced or substituted by other food ingredients, but rice has its own value for people who are accustomed to eating rice and cannot be easily replaced by other food ingredients. This study aims (i) to know the effect, and (ii) to get the best dose of granule organic fertilizer on the growth and yield of rice plants of Ciherang Varieties on lebak lowland. This research was conducted in Harusan Village, Amuntai Tengah District, North Hulu Regency, from February to May 2011. This study used a single randomized block design (RBD). The factors studied were 5 levels of granule organic fertilizer, namely: g0: 0 ton.ha-1, g1: 1 ton.ha-1 equivalent to or 8.571 g per clump or 0.3 kg per plot. g2: 2 ton.ha-1 is equivalent to 17.142 g per clump, or 0.6 kg per plot. g3: 3 ton.ha-1 is equivalent to 25,714 g per clump, or 0.9 kg per plot. g4: 4 ton.ha-1 is equivalent to 34.285 g per clump, or 1.2 kg per plot. The factors studied were as much as granule organic fertilizer. The results showed that the treatment of granular organic fertilizer dosage did not affect plant height, many tillers, but the treatment had a significant effect on the number of filled grain per clump. The treatment of granulated organic fertilizer dosage of 2 tons.ha-1 is equivalent to 17.142 g per clump, which is the best dose of the number of filled grain per clump

This study aimed to observe the growth and yield of Chiherang rice (Oryza sativa L) and weeds in response of different planting methods and weeding frequencies. We conducted the study in Semampir, Argorejo, Sedayu Sub-district, Bantul District on April until August, 2018. We arranged field study using randomized complete block design in 3x2 factorials with 3 times repetition. First factor was Jajar legowo (J) stratified as 3 levels; 2:1 (J1), 4:1 (J2), dan 6:1 (J3). Second factor was weeding frequency in 2 levels which were 2 times in 14 and 70 hst (P1) and 3 times in 14, 49 and 70 hst (P2). Observed variables include Ciherang rice growth (plant height, total tillers, percentage of productive tillers, fresh and dried weight of each plant), components of rice yield (grain dry weight of each harvest, percentage of filled grains, yield of each hectares), and weeds (type of weeds, fresh and dry weight of weeds). We analyzed results using variance analysis with significant level of 5%, followed with 5% DMRT test. We found that application of jajar legowo planting method and weeding frequency do not correlates with all growth and weeding frequency variables of Ciherang rice and weeds. 2:1, 4:1 and 6:1 jajar legowo planting methods do not show significant impact both on Ciherang rice growth and yield, and also weeds. Both 2 times (14 and 70 hst) and 3 times (14, 49 and 70 hst) also do not have significant impact on all variables observed.Keywords: Jajar Legowo, Weeding Frequency, Ciherang Rice

The growth and production of rice (Oryza sativa L.) variety IR841 were evaluated in response to arbusular mycorrhizal fungus (AMF) inoculation. Four strains of AMF (Acaulospora spinosa, BEN 10, Glomus mosseae and G. hoi) were tested at 1.96 x 105 ; 3.91 x 105 and 7.82 x 10 5 spores/ha during two growing seasons 2016 and 2017, in a complete random block design. Uninoculated plants and plants fertilized with chemical fertilizer were used as control. The experiments conducted for 19 weeks including 5 weeks in nursery and 14 weeks in field tests showed better development and production of rice in inoculated plants compared to uninoculated controls. The tested rice variety was highly dependent on arbuscular mycorhization. For each strain the rate of mycorhization was dose dependent. The different growth parameters such as the height of the plant, the development of the root system, the total biomass, the number of tillers, the number of fertile panicles per plant, the number of paddy grains per panicle and the paddy grain yield, were positively correlated with the rate of root mycorhization. This study showed that biofertilizers based on mycorrhizal fungi provide important benefits to the plant, and can be used to improve the growth and yield of rice in Togo. The results are discussed in terms of usingAMF as alternative to chemical fertilizer in rice production system.

Effect of nitrogen and bio-fertilizer on growth and productivity of hybrid rice (cv. PHB 71) was assessed during dry seasons of 2017 and 2018 at Research Farm of BCKV under new alluvial zone of West Bengal. The experiment was laid out in factorial randomized block design with 12 treatment combinations having 4 levels of N and 3 types of bio-fertilizer replicated thrice. Application at 180 kg N/ha produced tallest plants at 90 DAT with maximum LAI (60 DAT), DMA (90 DAT), tillers/hill (90 DAT) and CGR (30-60 & 60-90 DAT). The same N rate resulted in highest panicles/m2, panicle length, panicle weight, filled grains/panicle and 1000-grain weight. A decrease in N dose from 180 to 150 kg/ha caused reduction in all those yield components; however, the variation was non-significant except for number of panicles/m2. Maximum grain yield, straw yield and harvest index was also achieved with 180 kg N/ha accounting 120.1, 34.9 and 32.8% more than the values obtained with zero-N; however, it was statistically at par with the yields and HI obtained with 150 kg N/ha. The Azospirillum application increased all the growth parameters, yield components and yield of hybrid rice over other tested bio-fertilizers (Azospirillum > PSB > K mobilizer), accounting 5.9 and 8.8% more than the yields obtained with PSB and K mobilizer. The interaction of N and bio-fertilizer exerted significant effect on growth attributes but failed to record any significant variations in yield components and yield of hybrid rice. The maximum economic benefit was achieved with combined application of 180 kg N/ha and Azospirillum.
